DETAILED DESCRIPTION

[0031] The specific implementation of the utility model is described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model. Example 1:

[0032] As Figures 1-7As shown, the compressor moving plate bearing that can be quickly disassembled and assembled in this embodiment includes a compressor moving plate body 1, a bearing body 2 disposed at the center of the compressor moving plate body 1, and a moving block 31 disposed on the outer circumference of the bearing body 2. The center of the compressor moving plate body 1 is provided with a mounting hole 11 that can penetrate through its upper and lower sides. Several insert blocks 12 are arranged longitudinally and equidistantly on the inner wall of the mounting hole 11.

[0033] The bearing body 2 includes a bearing outer ring 21 that can be installed inside the mounting hole 11. A relief groove 22 is provided on the outer circumferential surface of one end of the bearing outer ring 21. An adaptation groove 221 that can be adapted to the insert block 12 is provided on one side of the bottom end of the relief groove 22.

[0034] An arc-shaped limiting block 23 for mounting the movable block 31 is provided on the side of the positioning groove 22 away from the adapter groove 221; a reset spring 24 for driving the movable block 31 to reset is provided inside the arc-shaped limiting block 23.

[0035] To enable rapid assembly of the bearing body 2 with the compressor moving plate body 1, the mounting hole 11 is first placed near one end of the bearing body 2. Then, pressure is applied to one side of the compressor moving plate body 1, causing the insert block 12 inside the mounting hole 11 to press against the moving block 31. This allows the moving block 31 to slide along the outside of the arc-shaped limiting block 23, thus removing it from the top of the adapter groove 221. At this point, the top of the adapter groove 221 is open. The insert block 12 continues to move until it is fully inserted into the adapter groove 221. Once the insert block 12 is fully inside the adapter groove 221, one end of the moving block 31 separates from the side of the insert block 12, and is then reset by the return spring 24. At this point, the bottom of the moving block 31 is in close contact with the top of the insert block 12, preventing the insert block 12 from falling out of the adapter groove 221. This improves the assembly efficiency of the compressor moving plate and the bearing.

[0036] like Figure 6 As shown, a first inclined surface 13 is provided on one side of the bottom end of the insertion block 12; a second inclined surface 311 is provided on one end of the moving block 31, which can be adapted to the first inclined surface 13. To achieve linkage between the insertion block 12 and the moving block 31, the first inclined surface 13 is inclined on one side of the bottom end of the insertion block 12, and the second inclined surface 311 is inclined on the top of one end of the moving block 31. When the insertion block 12 moves longitudinally, the first inclined surface 13 on one side of the bottom end of the insertion block 12 will gradually approach the moving block 31 and then contact the second inclined surface 311 near the top end of the moving block 31. When the first inclined surface 13 contacts the second inclined surface 311, the downward pressure on the insertion block 12 will squeeze the second inclined surface 311 through the first inclined surface 13, and at the same time, the second inclined surface 311 will convert the downward pressure into a lateral thrust. At this time, the lateral thrust will push the moving block 31 to slide along the outside of the arc-shaped limiting block 23.

[0037] As shown in Figure 3 , Figure 4 , Figure 5 and Figure 7 , the center of the arc-shaped limiting block 23 is provided with an arc-shaped mounting groove 232 for mounting the return spring 24; the center of the inner circle of the moving block 31 is provided with a second clearance hole 34, and the inside of the second clearance hole 34 is provided with an arc-shaped insertion rod 33 which can be inserted into the inside of the arc-shaped mounting groove 232, and one end of the return spring 24 can be in close contact with one end of the arc-shaped insertion rod 33.

[0038] In order to realize the automatic reset of the moving block 31, the arc-shaped mounting groove 232 is formed at the center of the arc-shaped limiting block 23, and then the return spring 24 is mounted in the arc-shaped mounting groove 232, so that the return spring 24 can always be in a relatively stable horizontal state. The arc-shaped insertion rod 33 is arranged at the center of the inner circle of the moving block 31, and then the arc-shaped insertion rod 33 is inserted into the inside of the arc-shaped mounting groove 232, so that one end of the return spring 24 is in contact with the end of the arc-shaped insertion rod 33 away from the moving block 31. The return spring 24 can drive the moving block 31 to move synchronously while pushing the arc-shaped insertion rod 33 to move along the inside of the arc-shaped mounting groove 232. The automatic reset of the moving block 31 is effectively realized.

[0039] As shown in Figure 4 , Figure 5 and Figure 7 , the top and bottom of the arc-shaped limiting block 23 are provided with arc-shaped limiting grooves 231 for limiting; the top and bottom of the second clearance hole 34 are provided with arc-shaped sliding rails 341 which can be matched with the arc-shaped limiting grooves 231. In order to ensure the stability of the moving block 31, the arc-shaped sliding rails 341 which can be slidingly matched with the arc-shaped limiting grooves 231 are arranged at the top and bottom of the second clearance hole 34 respectively. When the moving block 31 moves, the moving block 31 will drive the arc-shaped sliding rails 341 to move along the arc-shaped limiting grooves 231, effectively avoiding the deviation of the moving block 31 during movement.

[0040] As shown in Figure 4 , Figure 5 and Figure 7 , the end of the top of the moving block 31 away from the second inclined surface 311 is provided with a reserved slot 32, and the reserved slot 32 is used for pulling the moving block 31 to move along the outside of the arc-shaped limiting block 23. By arranging the reserved slot 32 at the end of the top of the moving block 31 away from the second inclined surface 311, when it is needed to disassemble the bearing body 2 from the mounting hole 11, the tool is inserted into the reserved slot 32, and then the tool drives the moving block 31 through the reserved slot 32, so that the moving block 31 is separated from the top end of the reserved slot 32. At this time, the compressor moving disc body 1 is lifted upwards, and the quick disassembly can be realized. Example 2:

[0041] Compared with the embodiment 1, as shown in Figure 3 and Figure 4 The material of the bearing outer ring 21 is made of high-temperature alloy steel. In order to ensure the stability of the bearing outer ring 21 in the working state, the bearing outer ring 21 is made of high-temperature alloy steel, which utilizes the high-temperature stability and high-strength characteristics of the high-temperature alloy steel to avoid the deformation of the bearing outer ring 21 caused by high temperature in the high-speed state. Effectively improve the hardness and anti-deformation ability of the bearing outer ring 21, ensure the stable operation and precision of the bearing.

[0042] As shown in Figure 4 The material of the moving block 31 is made of nickel-based alloy or cobalt-based alloy. In order to avoid damage to the moving block 31 in extreme working environment, the moving block 31 is made of nickel-based alloy or cobalt-based alloy, which makes full use of the corrosion resistance and high-temperature strength characteristics of the nickel-based alloy or cobalt-based alloy, so that the moving block 31 can maintain stable form in extreme environment.

[0043] As shown in Figure 7 The material of the reset spring 24 is made of titanium alloy. In order to ensure the elasticity of the reset spring 24, titanium alloy or nickel-based alloy is used as raw material, which utilizes the dense oxide film formed by titanium alloy or nickel-based alloy in high-temperature environment to effectively resist oxidation and corrosion. So that the reset spring 24 can maintain high strength and stiffness, effectively ensuring the resilience of the reset spring 24.

[0044] The above is only the preferred embodiment of the present application, it should be pointed out that, for those skilled in the technical field, without departing from the technical principle of the present application, can make a number of improvements and decorations, these improvements and decorations should also be regarded as the protection scope of the present application.
